Strange waves rippled around the world, and nobody knows why

On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world.

The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away.

These waves didn't just zip by; they rang for more than 20 minutes. And yet, it seems, no human felt them.

Only one person noticed the odd signal on the U.S. Geological Survey's real-time seismogram displays. An earthquake enthusiast who uses the handle @matarikipax saw the curious zigzags and posted images of them to Twitter. That small action kicked off another ripple of sorts, as researchers around the world attempted to suss out the source of the waves. Was it a meteor strike? A submarine volcano eruption? An ancient sea monster rising from the deep?

“I don't think I've seen anything like it,” says Göran Ekström, a seismologist at Columbia University who specializes in unusual earthquakes.

Mystery of the ‘rumble in the Indian Ocean’ is SOLVED: Strange seismic waves that shook the world on November 11 were ‘almost certainly’ triggered by an underwater volcano

By Cheyenne Macdonald For Dailymail.com and Harry Pettit For Mailonline

November 28, 2018

*Low-frequency waves around world that rumbled for 20 minutes were detected
*Researchers say there was no large earthquake that corresponds with the waves
*Internet sleuths have traced the origin to a spot just off the shores of Mayotte

Mysterious seismic waves picked up by monitoring stations from Madagascar to Canada were most likely caused by a volcano under the seabed, an earthquake expert claims.

A low-rumbling that could not be felt above ground was detected on November 11 and narrowed down the origin to a region just off the coast of the island of Mayotte.

They were similar to those typically seen after large earthquakes, which are known to travel great distances - but, no such earthquake took place.

Theories as to what caused the cryptic rumble ranged from a slow earthquake to an undetected meteor strike.

But one scientist who has studied the charts told MailOnline that the trembling was ‘almost certainly’ caused by a low-level underwater volcanic eruption off the northeast of Mayotte.

Anthony Lomax, an independent seismology consultant, said the shakes were ‘almost certainly’ caused by undersea activity, not very deep under the seafloor, to the northeast of Mayotte.

‘There has been ongoing low-level seismic activity there since May,’ he told MailOnline.

‘Inflation/deflation and collapse of volcano calderas, and movement of magma under a volcano can produce a wide variety of seismic signals, including long period and repetitive waves like those observed November 11.’

The monotone ‘ring’ was picked up by seismographs almost 11,000 miles (18,000 km) from Mayotte, and were spotted by chance.

A New Zealand based Earthquake enthusiast who goes by the handle @matarikipax noticed unusual seismology readings from the US Geological Survey.

The agency publishes all of its recordings for free online, allowing anyone across the globe to trawl through its data.

‘This is a most odd and unusual seismic signal. Recorded at Kilima Mbogo, Kenya,’ @matarikipax wrote on Twitter on November 11.

‘The signal can be seen all around the world.’ ...”

I will go with Malaysia Airlines Flight 370 and the old TV series LOST.

Flight 370 crashed on an Island in that area, but the island does not necessarily and always exist in this dimension. In fact, the Island can be moved in space and time.

However, on the island, the crash victims found and old Commodore 64 on the island’s underground research lab and are now sending out Distress Signals because John Locke is driving them crazy.

Some people saw the wave...
